Fig. 5 is a schematic view showing the structure of the rectangular lock of fig. 1 in the mechanical lock cylinder unlocked state. Fig. 6 is a perspective view showing the electronic lock cylinder, the mechanical lock cylinder and the hard ball of fig. 5. Referring to fig. 1 to 6, a rectangular lock according to a first embodiment of the present invention includes a lock body 1, a cross beam 2, an electronic lock cylinder 3, a mechanical lock cylinder 4, and a hard ball 5.

The lock body 1 accommodates an electronic lock cylinder 3, a mechanical lock cylinder 4 and a hard ball 5. The beam 2 is provided with a beam matching part 21 matched and locked with the hard ball 5, and when the beam matching part 21 accommodates part of the hard ball 5, the hard ball 5 is meshed with the beam 2.

Fig. 8 is an exploded view of the electronic lock cylinder of fig. 1. Fig. 9 is a cut-away view of the electronic lock cylinder of fig. 8. Please refer to fig. 8 and 9. The electronic lock cylinder 3 is connected with a first cam 31, and the first cam 31 is cylindrical. The first cam 31 is driven by a motor. The electronic lock cylinder 3 includes a first cam 31, a mating cover 32, a third cam 33, a return spring 34, and a motor 30.

The first cam 31 is fixedly connected with a connection pipe 311 for accommodating the fitting cap 32 and a part of the motor 30. The inner wall of the connection pipe 311 is provided with a connection pipe hole 310 corresponding to the position of the steel ball 330. The matching cover 32 is sleeved outside the third cam 33, and meanwhile, the matching cover 32 is fixedly connected with the stator of the motor. The third cam 33 is sleeved outside the output shaft of the motor 30, the third cam 33 is accommodated in the matching cover 32, and the matching cover 32 is provided with a through hole 320 corresponding to the steel ball 330 in position.

The third cam 33 has a recess portion capable of accommodating a part of the steel ball 330, and when the steel ball 330 is accommodated in the recess portion, the distance between the center of the ball 330 and the axis of the rotor and the radius of the steel ball 330 are smaller than the outer diameter of the mating cover 32. The motor 30 is fixed with a cam stopper 30a. The third cam 33 further has an engaging portion 33a which engages with the cam restricting portion 30a so that the third cam can rotate only within a certain angular range. Thus, the rotation angle of the cam is limited by the cam limiting part 30a, and the motor does not need to adopt a controller for controlling the rotation amplitude of the rotor.

Both ends of the return spring 34 are respectively connected and fixed with the motor stator 30 and the third cam 33. The torque direction of the return spring 34 is counterclockwise. Thus, a circuit for controlling the motor to rotate clockwise is not needed. The return spring 34 is preferably a torsion spring.

When the steel ball 330 does not enter the coupling tube hole 310, the coupling cap 32 may rotate within the coupling tube 311. When the motor rotates anticlockwise, the protruding part of the third cam 33 pushes part of the steel balls 330 into the connecting tube hole 310 from the through hole 320 of the matching cover 32, at this time, the steel balls 330 engage the first cam and the motor stator, and the first cam can be driven to rotate by rotating the motor shell.

The mechanical lock cylinder 4 is connected with a transmission part 41a and a second cam 41 for accommodating the transmission part, and the transmission part 41a is used for driving the second cam 41 to rotate. The rotation axis of the first cam 31, the rotation axis of the transmission part 41a and the sphere center of the hard ball 5 are positioned on the same plane A. The center of the second cam 41 and the rotation axis of the transmission portion 41a are located on the same plane B. The second cam is in a sphere segment shape. The cross-sectional shape of the transmission portion 41a is rectangular.

Fig. 7 is a cross-sectional view of the second cam of fig. 1. Referring to fig. 7, the second cam 41 is provided with a transmission matching portion 410 matching with the transmission portion 41a, and the transmission matching portion 410 is a through hole. The transmission engagement portion 410 has a rectangular cross section, and the transmission engagement portion 410 has a pair of limiting walls 411 and a connecting wall 412 connecting the limiting walls, and the second cam 41 is movable parallel to the limiting walls 411. The second cam 41 has a cross section including a circular arc edge 41b having an arc degree greater than pi and a straight edge 41c connecting the ends of the circular arc edge 41 b. The cross-sectional edge of the first cam 31 is the same as the cross-sectional edge 41 of the second cam 41.

The locking and unlocking of the rectangular lock of the invention is divided into the following three cases:

locking state: referring to fig. 1 and 2, when the limiting wall 411 is parallel to the plane a, the first cam 31 may press the second cam 41 to make the hard ball 5 engage the cross beam 2.

Unlocking state of the electronic lock cylinder: referring to fig. 3 and 4, when the limiting wall 411 is parallel to the plane a, the linear edge of the first cam 31 contacts the second cam 41 to separate the hard ball 5 from the beam 2.

Mechanical lock core unlocking state: referring to fig. 5 and 6, when the limiting wall 411 is perpendicular to the plane a, the hard ball 5 is separated from the beam 2.

In this embodiment, the hard ball, the first cam, and the second cam are made of steel, the mechanical lock core is unlocked by a mechanical key, and the electronic lock core can be unlocked by fingerprint, bluetooth, radio, etc.

Fig. 10 is an exploded view of a transmission part and a transmission matching part according to a second embodiment of the present invention. In this embodiment, the cross-section of the second cam is an elliptical columnar structure, and the driving engagement portion 410 is a groove.

In this embodiment, the edge of the second cam is the same as the edge of the cam in the first embodiment, and the second cam is fixedly connected with a rod-shaped transmission matching portion 410, and the transmission portion 41a has a block structure with a groove.
